As the thread is about cleaning solution I think I can piggyback my issue onto it.

I have a white rubber hose that I lead from the tap to the Nova washer slot. The hose was looking a bit stained/dirty so I have submerged it into dilute bleach and it has done a great job except for one brown stain that is particularly stubborn. I am pretty certain that the stain is developer so in addition to the bleach, I sprayed it last night with Nova TarBuster but it has made almost no difference to the slight lessening of the stain already achieved from dilute bleach

All I can think of is dunking the affected part in much stronger bleach and wait and see what happens.

However if anyone has a better idea then please let me know. As the hose is rubber it may have soaked into the rubber too deeply to remove but as I have said the stain is less but it has taken a couple of days already to even lighten the brown slightly

Thanks

Mike

Default Stubborn stains

I have a C41 developer stain on the kitchen floor which is the usual cushion flooring. It was on there for no more than15 mins before I noticed the mark and wiped it up. Fortunately the flooring is charcoal grey so it doesn't show too badly because nothing I have tried will even make it fade.

Of the two strongest I have used Kodak stop bath which is exceptionally concentrated with acetic acid base (1-63) and neat Domestos. Bother were left on the site overnight but no joy. It is I am afraid a permanent scar.

Thanks John. I have now got the tip of the hose where it is stained in a narrow 45ml graduate with a bleach that is about 1:1

If that doesn't shift it or shows major signs of beginning to remove it by tomorrow then that only leaves cutting a couple of inches of hose from the nozzle end and refitting the nozzle

In fact that would be the quick and easy solution but I hesitate to do that because I have no idea how the nozzle is fixed to the tube and whether if I can remove it successfully I can re-attach it to the hose so there is no leakage

Thank you folks.
Two days in water and washing up liquid.
Then about four days in bleach and water.
Cleaned the dishes and a few polythene measuring beakers.
Even took the old indelible pen writing off the beakers.

Excellent. Many thanks.

I have used Steradent for paterson spirals which works well soaking overnight in a strong solution, possibly work for plastic dishes too.

Just for info: I had to cut the stained bit of my white hose out but it was simple to re-attach the nozzle to the remaining hose. I suspect that almost undiluted bleach would have worked after maybe weeks

Clearly white rubber that has lain under a slightly leaking Nova developer slot nozzle for a while may be a stain too far
